1 Claim.

This invention relates to handle fastening devices for tools, and itsprimaryobject is to provide a device that is designed for a tool havinga head which includes a tapered eye or socket and a handle having atapered outer end portion fitting the socket to set up a wedging actiontherewith, such as for example a pick, grub hoe, mattock or the like,and my device is of flat ring like formation to surround and fit thehandle for engagement with the inner shoulder of the socket portion ofthe head, and includes means about the inner periphery thereof topenetrate the handle when the device is driven against said shoulder, soas to cooperate with said wedging action to prevent any possibility ofcasual removal or displacement of the head with respect to the handle.

A further object is to provide a handle fastening device that is simplein construction, easy to apply, inexpensive to manufacture and extremelyefficient in use and. service.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behere.- inafter fully described, illustrated in the accomtion.

plain but they may be beveled to provide cutting V shaped penetratingteeth 2, slightly bent for dis posal at an angle beyond theouter face ofthe body, as best shown in Figure 4, and it will be understood that theshape, size and number of teeth may vary, providing theyhavepenetratingpoints 3, asthe essential, feature of the device is for the teeth to setup abitingengagement The teeth are shown as being edges.

From the above description and the disclosure in the drawing, it isbelieved that the use of my device will be obvious, but it might bementioned that the head of the tool is first applied to the handle inthe usual manner, that is from the hand gripping end thereof and isdisposed in contact with the enlarged tapered outer end por- The devicewith the teeth outermost is then applied to engage or substantiallyengage the inner shoulder of the socket portion of the head, thenceanother tool head or member having a socket similar to the first toolhead is appanying drawing and specifically pointed out in the appendedclaim.

In describing the invention in detail, reference will be had to theaccompanying drawing wherein like characters denote like orcorresponding,

9 parts throughout the several views, and in which: l

Figure 3 is aview of the device per se.

Figure 4 is a sectional view taken approximately on line 4-4 of Figure3, looking in the direction of the arrows. I

, Referring to the drawing in detail, it will be noted that I haveillustrated my device as being used for fastening the head A of amattock to its wood handle B, but it will be obvious that it can be usedon any kind of tool including a socketed head for wedging engagementwith its handle.

The device ismade into a single piece from relatively thin plate orsheet metal to provide a relatively wide ring like body I which in theform shown'is oval shape to have abinding fit with thehandle B at thejuncture of the enlarged course then removed.

plied to the handle, with the outer shoulder of the socket portion ofthe latter tool head or member innermost, and is given a hammeringaction against the device, thus it will be seen that the first tool headis driven in positive wedging' engagement with the handle and the teethare caused to penetrate the handle, so as to cooperate with the wedgingaction and thereby prevent any possibility of casual removal ordisplacement ofthe first, tool head from the handle. The second toolhead or member is of Itis thought from the foregoing description thatthe advantages and novel features of the invention will be readilyapparent.

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts, provided thatsuch changes fall within the scope of the appended claim.

What I claim is: a g A handle fastening device fora tool provided with ahead having a tapered socket portion and a handle having an enlargedtapered outer. end

, portion fitting the head to set up a wedging at:-

tion therewith, and said device comprising a relatively wide thin ovalshaped plate like ringto fit and surround the handle for engagement withthe inner shoulder of the socket portion, and substantially triangularshaped teeth formed on i and extending from and about the entire innerrespect to the handle.

periphery of the ring at a slight angle beyond the outer face thereof topenetrate the handle for cooperation with the wedging action to preventcasual removal or displacement of the head with ALFRED D. JONES.
